The position of the longitudinal axis of the renal pelvic system is of special significance in the diagnosis of renal pelvic reduplications, horseshoe kidneys and space occupying processes of the kidney. The present study of 143 normal infant urograms shows that the angle between the axis of the renal pelvis and the axis of the vertebra is dependent on age. While in the newborn a negative angle is a common finding, during adolescence the axis approaches the position we usually find in the adult.
肾盂系统纵轴的位置在肾盂重复畸形、马蹄肾及肾脏占位性病变的诊断中具有特殊意义。本项对143例正常婴儿尿路造影片的研究表明，肾盂轴与脊椎轴之间的夹角取决于年龄。新生儿中常出现负角，而在青春期，肾盂轴接近我们在成年人中常见的位置。
